'Patented Nov. 8, 1921.

Application filed November 8, 1920. Serial No. 422,421.

To oil lrho/m. t may concern.'

Be it known that we, Mnnrr L. CooHrcix and MARION E. lVoon, citizens ofthe United States, residing at Kansas City, in the county of Tyandotteand State of Kansas, have invented a certain new and useful Improvementin Rail-Joints, of which vthe following is a specification.

Our invention relates to rail joints. It relates particularly to a novelrail chair and a novel means for attaching two rails to the chair.

An object of our invention is to provide rail chair which is simple inconstruction, cheap to make, durable. and efficient in operation.

A further object of our invention is to provide novel means for securelyfastening two rails to a rail chair.

The novel features of our invention are hereinafter fully described andclaimed.

In the accompanying drawing, which illustrates the preferred embodimentof our invention.

Figure 1 is a perspective view of our im proved rail chair.

Fig. 2 is a perspective view of a U-bolt adapted to be used inconnection with the chair.

F ig. 3 is a side elevation of our improved rail chair shown inoperative engagement with two rails.

Fig. 4 is a top view of the same.

Fig. 5 is an end elevation. enlarged, of the same. one of the railsbeing shown in cross-section.

Similar reference characters designate similar parts in the ditte-rentviews.

Our improved rail chair is provided with a flat horizontal base 1adapted to be suported on a tie 2 to which the chair may be rigidlyattached in any desired manner, as by means of a spike 3 extendingthrough a vertical hole et in the base 1 adjacent to ne side edge of thebase 1. and by spikes extending through edge notches G in the oppositeside edge of the base.

The rail chair is provided with two flanges T and S which extendupwardly7 and inwardly and are adapted to bear upon the upper sides ofthe bases 9 of two rails. the adjoining end portions of which areadapted to rest upon the base 1. The flanges 7 and S extend from therail bases 9 upwardly at opposite sides respectively of and spaced apartfrom the webs 10 of the two rails. The upper ends of the flanges 7 and 8are, preferably, outwardly turned and bear against the under side of theballs 11 of the rails.

A horizontally disposed U-bolt provided with two screw threaded arms 12which are adapted to extend through the flanges 7 and S and through thetwo webs 10 of the rails is provided.

Respei'tively mounted on the threaded arms 12 are two nuts 13 adapted tobear against the outer side of the flange 8. The transverse portion 14of the U-bolt is adapted to bear against. the outer side of the flange7.

By employing a U-bolt for clamping the flanges 7 and 8 to the rails,possibility of the bolt being turned` by vibration is avoided. Havingthe flanges 7 and S spaced apart from the webs 107 when the nuts 13 aretightened, effects a spring clamping action of the flanges against therails, which spring clamping action tends to hold the nuts 13 from beingloosened through vibration of the parts.

B v having the flanges 7 and 8 bearing against the upper sides of thebases of the rails and against t-he under sides of the balls of therails, the flanges strongly reinforce the webs of the rails at the endsof the rails.

In applying a chair to the rails, the chair is slipped on to one end ofone of the rails, after which the adjoining end of the other rail isslipped between the flanges 7 and S in an endwise direction. U-holt. arethen passed through the holes provided therefor in the webs 10 and theflanges 7 and 8. The nuts 13 are then applied to the arms 19. and are soadjusted as to draw the flanges 7 and 8 toward each other, so as tocreate a spring clamping action of the flanges against the rails.

The base 1 of the chair is then spiked to the top of a tie 2` as alreadydescribed.

The U-bolt 14 serves also to hold the rails against, movement away fromeach other without any dependence being placed upon the flanges 7 and 8for effecting this function. such as would be required were two ordinarybolts substituted for the Ubolt.

le do not limit our invention to the structure shown and described, asmany modifi- The arms 12 of thecations, within the scope of the appendedclaim, may be made without departing from the spirit of our invention.

That we claim is:

In a rail joint, a rail chair having a flat base adapted to support thebases of two adjoining rails and having respectively adjacent toopposite ends spike openings, and having intermediate of said openingstwo flanges adapted to embrace the upper sides of the bases of the railsand the under sides of' the balls of the rails at opposite sidesrespectively of and spaced apart from the webs of the rails, the upperends of the flanges being outwardly turned and bear- U-bolt beingadapted to bear against the outer side of the other flange, whereby theflanges may exert a spring clamping action, substantially as set forth.

In testimony whereof we have signed our names to this specification.
